gfi CVE Vulnerabilities & Metrics

A remote code execution vulnerability in GFI Kerio Control 9.4.5 allows attackers with administrative access to upload and execute arbitrary code through the firmware upgrade feature. The system upgrade mechanism accepts unsigned .img files, which can be modified to include malicious scripts within the upgrade.sh or disk image components. These modified upgrade images are not validated for authenticity or integrity, and are executed by the system post-upload, enabling root access.

A missing authentication vulnerability in the GFIAgent component of GFI Kerio Control 9.4.5 allows unauthenticated remote attackers to perform privileged operations. The GFIAgent service, responsible for integration with GFI AppManager, exposes HTTP services on ports 7995 and 7996 without proper authentication. The /proxy handler on port 7996 allows arbitrary forwarding to administrative endpoints when provided with an Appliance UUID, which itself can be retrieved from port 7995. This results in a complete authentication bypass, permitting access to sensitive administrative APIs.

An authentication bypass vulnerability exists in GFI Kerio Control 9.4.5 due to insecure default proxy configuration and weak access control in the GFIAgent service. The non-transparent proxy on TCP port 3128 can be used to forward unauthenticated requests to internal services such as GFIAgent, bypassing firewall restrictions and exposing internal management endpoints. This enables unauthenticated attackers to access the GFIAgent service on ports 7995 and 7996, retrieve the appliance UUID, and issue administrative requests via the proxy. Exploitation results in full administrative access to the Kerio Control appliance.

GFI MailEssentials prior to version 21.8 is vulnerable to a .NET deserialization issue. A remote and authenticated attacker can execute arbitrary code by sending crafted serialized .NET when joining to a Multi-Server setup.

GFI MailEssentials prior to version 21.8 is vulnerable to an XML External Entity (XXE) issue. An authenticated and remote attacker can send crafted HTTP requests to read arbitrary system files.

GFI MailEssentials prior to version 21.8 is vulnerable to a local privilege escalation issue. A local attacker can escalate to NT Authority/SYSTEM by sending a crafted serialized payload to a .NET Remoting Service.

A vulnerability was found in GFI KerioConnect 10.0.6 and classified as problematic. This issue affects some unknown processing of the file Settings/Email/Signature/EditHtmlSource of the component Signature Handler. The manipulation leads to cross site scripting. The attack may be initiated remotely. The exploit has been disclosed to the public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.

An issue was discovered in GFI Kerio Control 9.2.5 through 9.4.5. The dest GET parameter passed to the /nonauth/addCertException.cs and /nonauth/guestConfirm.cs and /nonauth/expiration.cs pages is not properly sanitized before being used to generate a Location HTTP header in a 302 HTTP response. This can be exploited to perform Open Redirect or HTTP Response Splitting attacks, which in turn lead to Reflected Cross-Site Scripting (XSS). Remote command execution can be achieved by leveraging the upgrade feature in the admin interface.

GFI Archiver Store Service Deserialization of Untrusted Data Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of GFI Archiver. Authentication is required to exploit this vulnerability. The specific flaw exists within the Store Service, which listens on TCP port 8018 by default. The issue results from the lack of proper validation of user-supplied data, which can result in deserialization of untrusted data. An attacker can leverage this vulnerability to execute code in the context of SYSTEM. Was ZDI-CAN-24331.

GFI Archiver Telerik Web UI Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of GFI Archiver. Authentication is not required to exploit this vulnerability. The specific flaw exists within the product installer. The issue results from the use of a vulnerable version of Telerik Web UI. An attacker can leverage this vulnerability to execute code in the context of NETWORK SERVICE. Was ZDI-CAN-24041.

GFI Archiver Core Service Deserialization of Untrusted Data Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of GFI Archiver. Authentication is required to exploit this vulnerability. The specific flaw exists within the Core Service, which listens on TCP port 8017 by default. The issue results from the lack of proper validation of user-supplied data, which can result in deserialization of untrusted data. An attacker can leverage this vulnerability to execute code in the context of SYSTEM. Was ZDI-CAN-24029.

An issue was discovered in GFI Kerio Connect 9.4.1 patch 1 (fixed in 10.0.0). There is a stack-based Buffer Overflow in the webmail component's 2FASetup function via an authenticated request with a long primaryEMailAddress field to the webmail/api/jsonrpc URI.

File upload vulnerability in GFI Mail Archiver versions up to and including 15.1 via insecure implementation of Telerik Web UI plugin which is affected by CVE-2014-2217, and CVE-2017-11317.

A DOM based XSS in GFI Kerio Control v9.3.0 allows embedding of malicious code and manipulating the login page to send back a victim's cleartext credentials to an attacker via a login/?reason=failure&NTLM= URI.

Kerio Connect 8.0.0 through 9.2.2, and Kerio Connect Client desktop application for Windows and Mac 9.2.0 through 9.2.2, when e-mail preview is enabled, allows remote attackers to conduct clickjacking attacks via a crafted e-mail message.

Untrusted search path vulnerability in GFI Backup 3.1 Build 20100730 2009 Home Edition allows local users to gain privileges via a Trojan horse ArmAccess.dll file in the current working directory, as demonstrated by a directory that contains a .gbc or .gbt file. NOTE: some of these details are obtained from third party information.

Race condition in VIPRE Antivirus Premium 4.0.3272 on Windows XP allows local users to bypass kernel-mode hook handlers, and execute dangerous code that would otherwise be blocked by a handler but not blocked by signature-based malware detection, via certain user-space memory changes during hook-handler execution, aka an argument-switch attack or a KHOBE attack. NOTE: this issue is disputed by some third parties because it is a flaw in a protection mechanism for situations where a crafted program has already begun to execute

Buffer overflow in the HTTP management interface for GFI MailSecurity 8.1 allows remote attackers to execute arbitrary code via long headers such as (1) Host and (2) Accept in HTTP requests. NOTE: the vendor suggests that this issues is "in an underlying Microsoft technology" which, if true, could mean that the overflow affects other products as well.

lnss.exe in GFI Languard Network Security Scanner 5.0 stores the username and password in memory in plaintext, which could allow local administrators to obtain domain administrator credentials.

A bug in the HTML parser in a certain Microsoft HTML library, as used in various third party products, may allow remote attackers to cause a denial of service via certain strings, as reported in GFI MailEssentials for Exchange 9 and 10, and GFI MailSecurity for Exchange 8, which causes emails to remain in IIS or Exchange mail queues.

SMTP content filter engines, including (1) GFI MailSecurity for Exchange/SMTP before 7.2, (2) InterScan VirusWall before 3.52 build 1494, (3) the default configuration of MIMEDefang before 2.21, and possibly other products, do not detect fragmented emails as defined in RFC2046 ("Message Fragmentation and Reassembly") and supported in such products as Outlook Express, which allows remote attackers to bypass content filtering, including virus checking, via fragmented emails of the message/partial content type.
